Soil release polymer in detergent compositions containing dye transfer inhibiting agents to improve cleaning performance

Claim 1

A granular detergent composition comprising, by weight: (A) from about 1% to about 50% of a detersive surfactant (B) from about 1% to about 80% of a builder (C) from about 0.01% to about 10% of a polyamine N-oxide polymer; (D) from about 0.01% to about 10% of a copolymer of N-vinylpyrrolidone and N-vinylimidazole; and (E) from about 0.01% to about 20% of a sulfonated poly-ethoxy/propoxy end-capped ester oligomer comprising (i) from about 1 to about 2 moles of sulfonated poly-ethoxy/propoxy end-capping units of the formula (MO 3 S)(CH 2 ) m (CH 2 CH 2 O)(RO) n -- wherein M is a salt forming cation selected from the group consisting of sodium and tetraalkylammonium, m is 0 or 1, R is ethylene, propylene or a mixture thereof, and n is from 0 to 2; (ii) from about 0.5 to about 66 moles of units selected from the group consisting of: a) oxyethyleneoxy units; b) a mixture of oxyethyleneoxy and oxy-1,2-propyleneoxy units wherein said oxyethyleneoxy units are present in an oxyethyleneoxy to oxy-1,2-propyleneoxy mole ratio ranging from 0.5:1 to about 10:1; and c) a mixture of a) or b) with poly(oxyethylene)oxy units wherein said oligomer; poly(oxyethylene)oxy units have a degree of polymerization of from 2 to 4; provided that when said poly(oxyethylene)oxy units have a degree of polymerization of 2, the mole ratio of poly(oxyethylene)oxy units to total group ii) units ranges from 0:1 to about 0.33:1; and when said poly(oxyethylene)oxy units have a degree of polymerization of 3, the mole ratio of poly(oxyethylene)oxy units to total group ii) units ranges from 0:1 to about 0.22:1; and when said poly(oxyethylene oxy units have a degree of polymerization of 4, the mole ratio of poly(oxyethylene)oxy units to total group ii) units ranges from 0:1 to about 0.14:1; (iii) from about 1.5 to about 40 moles of terephthaloyl units; and iv) from 0 to about 26 moles of 5-sulfoisophthaloyl units of the formula --(O)C(C 6 H 3 )(SO 3 M)C(O)-- wherein M is a salt forming cation.
